PURPOSE:To prevent a stepout at switching time by outputting other exciting sequence data corresponding to the same counted value as a stored position of one exciting sequence data and then sequentially outputting the other sequence data. CONSTITUTION:Data from a CPU1 is transmitted to drivers PD1-PD4 to control stepping motors MY, MM, MC, MB. Four types of exciting states by 2-phase excitation system is presented in the memory of a CPU1 at every two steps of 1-2 phase excitation type, the exciting sequence data for applying the same exciting state by 1-2 phase exciting type is stored at the location corresponding to the stored location of one data of the exciting sequence data of 2-phase exciting type prepared by two. After the other exciting sequence data corresponding to the same counted value as the storing location of one exciting sequence data is output at switching time, the other exciting sequence data are sequentially output. |
